Pakistans misssile defence systems

This is a discussion on Pakistans misssile defence systems within the Space & Defense Technology forum, part of the Global Defense & Military category; Ha guys I was just woundering if anyone knows anything about Pakistans missile defence system and when Pakistan is going ...

Can you tell me if HQ-9 is actually based on US patriot system or Russian S-300 system?

When Pakistan actually purchased the system from China... any idea.

.

The Hongqi-9 (HQ-9) is a long-range, high-altitude, surface-to-air missile system developed and manufactured by China, designed to track and destroy aircraft, cruise missiles, air-to-surface missiles, and tactical ballistic missiles. It incorporates technology from the Russian S-300P (NATO: SA-10 Grumble), the U.S. Patriot missile, and preexisting Chinese systems. (1) At present, China is outfitting its Type 052C destroyers with a naval variant of the HQ-9.(2)

. It is important to note, however, that the HQ-9 has been in development since the mid-1990s. In 1993, China purchased a large batch of S-300P missiles from Russia, and allegedly obtained a copy of the U.S. Patriot missile from Israel (although Israel denies that such a transfer took place).(10) The Chinese immediately began incorporating the S-300P and Patriot technology into their own air and missile defense system, the HQ-9. In 1997, the U.S. Office of Naval Intelligence suggested that “technology from advanced Western systems may be incorporated into the HQ-9.”(11) That same year, an official at a Russian missile design bureau acknowledged that the HQ-9 would incorporate the Patriot guidance and propulsion systems, thus confirming U.S. suspicions.(12)

According to missile defense expert David A. Fulghum, “[the HQ-9] uses a seeker-aided ground guidance system. The seeker on the missile sends target data back to the ground, which then correlates the target data for an intercept.”(13) It is assumed that the HQ-9’s seeker is similar to the Patriot’s “Track-via-Missile” guidance system.(14) Such a system, if actually used by the Chinese, would allow the HQ-9 interceptor missile to fly straight toward its target and explode at the point of nearest approach, thus completely destroying the incoming ballistic missile (or aircraft) or knocking it far enough off course so that it misses its intended target. During the Persian Gulf War, the U.S. Patriot Advanced Capability-2 system, which employs “Track-via-Missile,” destroyed its targets between 40 and 70 percent of the time.

In addition to its land-based deployments, the HQ-9 has been recently modified to complement China’s burgeoning naval forces. Over the past few months, the People’s Liberation Army Navy (PLAN) hasoutfitted two Type 052C destroyers with naval variants of the HQ-9, estimated to have a range of 65 nautical miles. Each Type 052C destroyer (similar to the U.S. Aegis destroyer) has six vertical launchers carrying approximately 36 missiles, as well as a phased-array radar system.(15) Initial reports indicate that the naval HQ-9 has a range of 65 nautical miles. The Type 052C destroyers will most likely be based at either Guangzhou or Zhanjiang.(16)

In October 2003, it was announced that China had sold its FT-2000 anti-radiation system, which uses HQ-9 missiles, to Pakistan as part of the latter’s military buildup against India. Many U.S. defense analysts predict that, over the next few years, the HQ-9 and its variants will be aggressively exported throughout Asia, Europe, and the Middle East.

also there is news that pakistan is acquiring the HQ-17 along with the VERA-E systems.

very soon pakistan is going to get the RAM missile for it's naval ships.

.

I have read an article some where which states that VERA-E system has actually been leased to Pakistan (Not Sold). Can any one tell me what is the lease period plus how this system is integrated with existing defence systems such as HQ-9.
As far as I know VERA-A is just a 3D target tracking system based on sensors with Microwave link.
